WALL MOUNTED HOOK

CROCHET MURAL

English Abstract

A hook to be mounted to a friable wall
comprises a body and at least one main saber tooth
extending rearwardly from an upper portion of the body
and adapted to be driven into the wall for securing the
device thereto. The main saber tooth is arcuate and has
a pointed rear free end, and is adapted to be arcuately
driven into the wall. An arcuate and pointy secondary
saber tooth extends rearwardly from a lower portion of
the body for insertion into the wall before the main
saber tooth is inserted therein. The main saber tooth
defines a lower enlarged, and typically flat, load-
bearing surface for bearing against material of the wall.
The main saber tooth includes an upper transversally
curved surface. A hook member is provided on a front
part of the body for suspending items therefrom once the
hook has been mounted to the wall.

WALL MOUNTED HOOK
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to wall fixtures
and, more particularly, to a wall anchor for use
typically in friable materials, e.g. gypsum.
2. Description of the Prior Art
There are various wall anchors available on the
market, including plastic inserts which are hammered in a
hole previously defined in a wall with a fastener, such
as a screw, being then engaged in the plastic insert,
causing it to expand such that the assembly of the insert
and the fastener is set in the wall.
Toggle bolts also exist, wherein rotation of a
bolt causes wings to deploy behind the wall and to
ultimately abut the inside of the wall thereby firmly
anchoring the bolt to the wall.
Both these types of anchors necessitate that a
hole be previously drilled in the wall. On the other
hand, there exists wall anchors defining a pointed
cutting end and large threads, which are adapted to, in a
single step, be rotatively driven in the wall thereby
drilling their own hole in the wall with the large
threads of the anchor compacting the gypsum and becoming
firmly set therein. These types of anchors must be
installed by way of a screwdriver and typically by a
power driven screwdriver bit.
SUMMARY OF THE INVENTION
It is therefore an aim of the present invention
to provide a novel wall anchor of simple construction and
simple installation.
Therefore, in accordance with the present
invention, there is provided a wall mounted device,
typically for friable walls, comprising a comprising a
- 1 -

body adapted to be located on a visible side of a wall in
which said device is to be mounted, and at least one
saber tooth extending rearwardly from said body and
adapted to be arcuately driven into the wall for securing
said device thereto.
More particularly, said saber tooth extends
from an upper portion of said body, a secondary saber
tooth being extending from a lower portion of said body
for insertion into the wall before said saber tooth of
said upper portion is inserted therein.
Typically, a hook member is provided on a front
part of said body for suspending items therefrom once
said device has been mounted to the wall.
Preferably, said saber tooth includes a lower
substantially flat surface for bearing against wall
material provided in the wall.

mounted hook.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figs. 1 to 5 illustrate a one-piece wall
mounted hook H in accordance with the present invention.
The hook H comprises a body 10 adapted to be visible when
- 2 -

CA 02420722 2004-05-13
the hook H is mounted to the wall, and upper and lower
saber teeth 12 and 14, respectively, adapted to engage
the wall for securing the hook H thereto.
The body 10 includes a visible decorative front
surface 16 and a plane rear surface 18. The rear surface
18 is adapted to extend against the visible side of the
wall once the hook H has been mounted thereto. The front
surface 16 is provided, for instance, with a hook member
20 from which an article, e.g. a picture frame, clothes,
etc., can be suspended.
The upper and lower saber teeth 12 and 14 are
each curved and terminate rearwardly with respective
pointed tips 22 and 24.
The hook H is easily installed as follows . The
body 10 is pressed by hand against the wall such that the
lower saber tooth 14 pierces into the wall (e. g. through
the paper sheet of a gypsum panel forming the wall and
slightly through the powder portion thereof) and becomes
lodged therein without simultaneously driving the upper
saber tooth 12 into the wall.
Once the lower saber tooth 14 is in the wall
and with a lower end 26 of the body 10 abutting the wall,
an upper portion of the body 10, generally located at a
location indicated by reference numeral 28, is pressed by
hand (and possibly with a hammer for bigger hooks or if
wood is encountered in the wall)towards the wall such
that it pivots generally about the lower end 26 with the
upper saber tooth 12 being arcuately driven into the wall
thereby securely engaging the hook H to the wall.
A bottom surface 30 of the upper saber tooth 12
is enlarged and flat such as to provide a wide load
bearing surface between the upper saber tooth 12 and the
wall material (e. g. gypsum), thereby providing resistance
to the hook H ripping downwards through the wall
material, when a load is suspended from the hook member

20 thereof . A top surface 32 ~of the upper saber tooth 12
is rounded to facilitate the insertion of the upper saber
tooth 12 in the wall material.
The hook H can, for instance, be made of zinc
so that it can be die-casted.
In a variant (not shown) of the hook H, a
conventional leveller (i.e. a horizontal plate defining
saw teeth and having elbowed wings at the ends thereof
that can be nailed to an article, e.g. picture, such that
the picture can be mounted to the wall by suspending the
leveller attached thereto from a fastener previously
secured to the wall) is provide at each of its elbowed
wings with a rearwardly extending upper saber tooth. A V-
shaped member that extends downwardly from the horizontal
plate or from the elbowed wings has a lower saber tooth
extending rearwardly therefrom. This variant can thus be
secured to an article, e. g. a rear surface of a picture,
by first pressingly engaging the lower saber tooth in the
article, followed by pressingly engaging the upper saber
teeth therein.
